New Tech may read brain signal directly..

Researchers have developed a new technology that can help read brain signals directly and may also aid people with movement disabilities to better communicate their thoughts and emotions.
It involves a multi - electrode array implanted in the brain to directly read signals from a region that ordinarily directs hands and arm movements used , for example, to move a computer mouse. The algorithms translate those signals and help to make letter selections. "Our results demonstrate that this interface may have great promise for use in people." said Paul Nuyujukian , postdoctoral student at Stanford University in California , US. In an experiment conducted with monkeys, the animals were able to transcribe the passages from the national daily New York Times, and Hamlet, a tragedy drama written by William Shakespeare, at a rate of up to 12 words per minute. Using high performing algorithms, the animals could type more than three times faster than with earlier approaches.
